BOWLING PIN.

Application ined April s, 1924. serial No. 704,957.

To all whom t may concern:

Be it known that I, JOHN O. MILLER, a citizen of the United States,residing at Chi-- cago, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in Bowling Pins, ofwhich the following is a specification.

This invention relates to improvements in bowling pins, and its objectis to provide simple and eliicient means for protecting the base of thepin against wear and thereby maintain the pin in serviceablev conditionand prolong its life for a greater period than has been customaryherebefore.

Many bowling alleys are provided with pin setting devices which`comprise metal pins operating through the alley bed at the pin spotsthereon to project above'the surface of the bed for engaging openingsprovided for them in the bases of the pins. These metal pins registerthe bowling pins in correct position on the pin spots on the alley bed,after which they are lowered below the surface of the alley bed, so asnot to interfere with the game. The pin boy operates the setter toproject the setter pins above the surface' of the alley and then placesthe bowling pins on the metal setter pins; and after this has been donemany times, it is found that the metal pins wear the wood walls of theopenings so that correct setting and spotting of the bowling pins is notalways assured. This wear of the wall of the mold in the bowling pinmakes the pin setting operation more diliicult and laborious because themetal setter pin is somewhat pointed and will not enter a wornv holeproperly.

Furthermore, a bowling pin wears in service at the base so that it will'not stand properly, and means are sometimes provided where a number ofbowling alleys are installed, as well as at sales rooms for bowlingsupplies, for re-linishing the bowling pin base; some pins are providedwith reinforced bases, and other means have been proposed for reducingthe wear on the bases ofthe bowling pins.

My invention has for its object to provide simple means for reducingwear of the setter pins on the bowling pins, and also for reducing thenormal wear on the bases of the pins, whereby to prolong the efiicientservice of a bowling pin.

merely for the purpose of explaining the invention, and it will beunderstood that the inventlon can be embodied in any form of bowling pinfor which it is or may be adapted.

The drawing is an elevation of a duck p1n and shown partly broken awayand in section. The pin 1 shown in the drawing has anannular rubber ring2 which is now used on duck pins and constitutes no part of my mvention.A plug 3 is inserted in a bore 4t in the bottom of the pin and this plughas a flange 5 which is seated in a counter rbore 6. The plug has acentral opening 7 which is of a size and shape adapted to receive themetal registering pin of that form of bowling pin setter which comprisesa plurality of metal pins adapted to be projected upward through thealley bed and is known commercially as the simplex pin setter.

The plug is preferably made of liber 1n one piece and secured by glue inthe bores, but it can be made of other suitable materials and in morethan one piece and securely anchored in the bowling pin in any suitablemanner. The plug provides a fiber sleeve 3 which will resist the wear ofthe setter pin, and the flange 5 provides a bottom or base for the pinwhich will resist the wear to which the bottom or base of -a bowling pinis subjected. This base 5 preferably projectsslightly below the body thesize, shape and arrangement of the plug and that it can be used in otherbowling pins and secured in place in any suitable manner, and I reservethe rightl to make all such adaptations of and changes in theconstruction and arrangement of my. invention as fairly fall within thescope of the following claims.

I claim:

1. A bowling pin having a bore and a counter bore in its base, and awear preventing tubular plug seated in said bore and having a liangeseated in said counter bore.

2. A bowling pin having a bore and a counter bore in its base, a wearpreventing tubular plug comprising a sleeve seated in 4. A bowling pinhaving a, bore and a said bore, and an integral flange seated in counterbore in its base and a wear pre- 10 said counter bore. venting tubularplug comprising a sleeve 3. A bowling pin having a bore and a seated insaid bore, and an integral flange 5 counter bore inits base, and a wearpreventseated in said counter bore and projecting ing tubular plugseated in sald bore and below the body of the pin. counter bore, andlprojecting below the body of the pin.
